研究非旋转Destounis-Suvorov-Kokkotas黑洞周围测试粒子周期轨道及其引力波特性,通过轨道分类确定周期轨道行为,并分析变形参数对引力波信号的影响。

摘要:

本文研究非旋转Destounis-Suvorov-Kokkotas黑洞周围测试粒子的周期轨道及其产生的引力波。首先,我们分析圆轨道的性质,发现当变形足够大时,圆轨道可能消失。然后,利用轨道分类方法,用三元组整数描述各种周期轨道的zoom-whirl行为。我们还计算了不同周期轨道产生的引力波信号,揭示了变形对引力波的影响,这种影响可能被未来的空间引力波探测器捕捉到。

英文摘要:

In this paper, we investigate periodic orbits of test particles around a non-rotating Destounis-Suvorov-Kokkotas black hole and the resulting gravitational waves. Firstly, we examine the properties of circular orbits and find that circular orbits could disappear when the deformation is large enough. Then, using an orbital taxonomy, we characterize various periodic orbits with a triplet of integers, which describes the zoom-whirl behaviours. We also calculate the gravitational waveform signals generated by different periodic orbits, revealing the influence of the deformation on the gravitational wave, which can be potentially picked up by future space-based detectors.
